Is your Carbon correctly configured with the `storage-schemas.conf`
supplied by NAV? If not, your Whisper files will have been generated
with the wrong schemas, and that will impact the port stats worse than
the system stats - the default resolution in Carbon's config, I think,
is 1 minute interval data points, while NAV port counters are only
collected every 5 minutes, and displayed using Graphite's
derive-functions. That may cause your graphs to look pretty empty.

If your Whisper files have the wrong schema, the only useful way to fix
it is to install the correct Carbon `storage-schemas.conf`, restart
Carbon and delete all the Whisper files in the nav subtree.
